Linux has the same problem that other OS: "Multiple Vendor TCP Timestamp PAWS Remote Denial Of Service Vulnerability" published in 2005 by Noritoshi Demizu
If i send a SYN packet with high timestamp legitime user can not establish a connection with the victim server.
Kernel Tested : 2.6.21.5 , 2.6.11.12

Temporal solution: echo "0" > /proc/sys/net/ipv4/tcp_timestamp
Final solution: ??? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
